General

The TLP3440 photorelay consists of a photo MOSFET optically coupled to an infrared LED. It is housed in a

VSON4 package. The TLP3440 features low output capacitance of COFF, thus it is suitable for high frequency

signal applications.

Features

(1) Normally opened (1-Form-A)

(2) OFF-state output terminal voltage: 40 V (min)

(3) Trigger LED current: 3 mA (max)

(4) ON-state current: 120 mA (max)

(5) ON-state resistance: 12 Ω (typ.), 14 Ω (max)

(6) Output capacitance: 0.45 pF(typ.), 0.8 pF(max)

(7) Isolation voltage: 500 Vrms (min)
